Farfarout Dwarf Planet
Farfarout is very faint, and based on its brightness and distance from the Sun, the team estimates its size to be about 400 km across, putting it on the low end of being a dwarf planet, assuming it is an ice-rich object.

An earlier object - a dwarf planet - was called FarOut orbital distance of 124 AU, so this one has been named FarFarOut. The planetoid is four times as far away from the Sun as Pluto which has an average orbital distance of about 39 AU, at a massive distance of 140 astronomical units AU, making it the most distant object ever observed
They are on the hunt for Planet X, a small dwarf planet far beyond Pluto whose existence they proposed in 2014. So far, that search has yielded 62 distant objects, which make up about 80 percent
The object, if confirmed, would break his team's own discovery, announced in December 2018, of a dwarf planet 120 times farther out than Earth, which they nicknamed quotFarout.quot For now, they are jokingly calling the new object quotFarFarOut.quot quotThis is hot off the presses,quot he said during his rescheduled talk on 21 February.
Astronomers have identified the most distant known object in our solar system a dwarf planet nicknamed Farfarout that orbits far beyond Pluto. This remote mini-planet swings so far away from
Farfarout's inherent brightness suggests a world roughly 250 miles 400 kilometers wide, barely enough to qualify for dwarf planet status. But the size estimate assumes the world is largely made

NOIRLabNSFAURAJ. da Silva Dwarf planet Farout has an average orbital distance of 124 astronomical units, and it was named after an exclamation made by astronomer Scott Sheppard of the Carnegie Institution for Science. When he and his team discovered an even farther object, the progression was obvious.
Researchers currently think the dwarf planet is mostly made of ice, according to Space.com. Farfarout was first spotted in January 2018 by the Subaru Telescope on Maunakea on the island Hawai'i.
